ABC of Lighting

The right lighting in workplaces

The right lighting in the workplace is not only important for health and well-being, but also a matter of safety.

Does your workplace have the right lighting conditions? In our FAQ, we give you some helpful tips to ensure you do not fumble in the dark when it comes to workplace lighting!

In our online shop you will also find suitable lighting systems for your needs:

What are the risks of incorrect lighting in the workplace?

Inadequate lighting significantly increases the risk of accidents. In case of poor visibility, concentration and performance can also be reduced. Physical discomfort, such as burning eyes or headaches, not only affects well-being, but also has a negative impact on the frequency of errors in the work process.

Caution: Lighting that is too bright can also lead to problems when employees are blinded by unsuitable or misaligned lights.

Our infographic gives you a quick overview of the negative effects of wrong lighting in the workplace:

What do I need to know about installing and maintaining lighting systems? 

It is advisable to plan and maintain lighting systems by a qualified person. After the installation of the lighting system and the necessary firing time, compliance with the legal requirements should be checked by means of control measurements.

Periodic testing and maintenance is also necessary to correct any changes in the lighting parameters, as well as to correct any contamination or damage.

What can I do to avoid glare?

In order to prevent glare, lighting should be selected to provide adequate visibility in work areas but operating conditions must also be considered. It may also be helpful to reduce differences in brightness between the glare source and the environment (for example due to bright ceilings and walls) as well as reflections due to matt surface design.

Lighting that offers a wide range of adjustment and positioning options are ideal here. In our online shop you will find practical models for installation in the office, on drawing tables or in workshops.

What to do in the case of power failure? 

If your general lighting system fails, emergency lighting should already be installed to help avoid dangerous situations. 

When planning and installing emergency lighting systems within your business, DIN EN 1838 and DIN EN 13032-3 should be observed.

Which lighting levels need to be observed? 

 "The same light for all" is not an adequate solution in workplaces. Because it depends on the individual visual task, how much light is needed in the workplace. A general lighting system ensures a uniform illumination of the entire work area, but does not take into account the lighting requirements of individual room sections or workstations. Appendix 1 of the ASR A3.4 specifies the minimum values ​​to be observed for the illuminances and color reproduction indices for the different areas.

Table: Recommended lighting levels:

Workspaces, jobs and activities Lux Illuminance lx Color rendering index Ra
Traffic areas and corridors without vehicle traffic 50 40
Traffic areas and corridors without vehicle traffic in the area of ​​paragraphs and steps 100 40
Traffic areas and corridors with vehicle traffic 150 40
Shipping and packaging areas 300 60
Storage rooms for identical or large-scale storage goods 50 60
Storage rooms with search for non-identical storage 100 60
Storage rooms with reading tasks 200 60
Color test, control 1000 90
Laboratories, measuring stations 500 80
Trimming, finishing, control work in the chemical, plastics and rubber industries 750 80
Manufacture of tools and tools in metalworking and processing 750 60
Surface treatment and varnishing in metalworking and processing 750 80
Tool-. Gauging and device construction, precision and micromechanics in metalworking and processing 1000 80
Painting: Repair, inspection in the automotive industry 1000 90
Cable and wire production in the electrical industry 300 80
Impregnation of coils, electroplating in the electrical industry 300 80
Rough assembly work in the electrical industry, e.g. Large transformers 300 80
Medium-size assembly work in the electrical industry, e.g. Switchboard 500 80
Fine assembly work in the electrical industry, e.g. phones 750 80
Very fine assembly work in the electrical industry, e.g. measuring instruments 1000 80
Electronic workshops, testing, adjustment 1500 80
Quality control in woodworking and processing 1000 90


At no point in the area of the workplace may the temperature be 0.6 times lower than the average illuminance. The lowest value must not be within the range of the main vision task.

If minimum illuminance levels of more than 500 lux are stipulated, they do not necessarily have to be achieved at the entire workplace, but only at the partial surfaces relevant to the visual task. Partial lighting can be used, for example, when there is a special visual task (working with small parts, short observation periods) or when adaptation to the individual's vision of the employees is necessary. Here, for example, the use of additional workplace lighting is recommended.


The following infographic illustrates the different lighting requirements in a workshop:

Who is responsible for lighting in the workplace? 

The employer is expected to set up workplaces in such a way that there are no health hazards for the employees. This also includes an adequate lighting for individual visual tasks.

Within the scope of a risk assessment, it is necessary to determine and regularly check whether the workstations are suitably lit during operation. This can be determined with a corresponding measuring device (luxmeter).

Is daylight sufficient?

Daylight increases well-being but in practice it is not always sufficiently available at the right time or place. An additional artificial lighting system is therefore usually required. In our online shop you will find many lighting systems including wall and ceiling lights, tube lights, emergency lights and flashlights. Many products are also available in ex-protected design.
